Tight ultrafiltration (UF) has increasingly been developed to overcome the low selectivity of conventional UF membranes towards soluble contaminants. In this work, a tight structure polysulfone-based (PSf) membrane was prepared by blending PSf with polyethylene glycol (PEG400), ZnO nanoparticle (ZnO-Np), and acetone (Ac) in dimethylacetamide (DMAc). The influences Ac/DMAc ratio (1: 15 1:25) PEG...

The aim of this study was to develop and optimize Trimetazidine dihydrochloride (TM) controlled porosity osmotic pump (CPOP) tablets of directly compressed cores. A 2(3) full factorial design was used to study the influence of three factors namely: PEG400 (10% and 25% based on coating polymer weight), coating level (10% and 20% of tablet core weight) and hole diameter (0 "no hole" and 1 mm). Ot...

Bacterial cellulose (BC) is one of the current natural materials at edge innovation in engineered living (ELMs) research due to its ease growth and outstanding properties as a hydrogel. One main limitations this material, however, quick dehydration open environments water molecules leave porous network. Here we show that other solvents with higher evaporation temperatures, namely glycerol polye...

Palladium nanoparticles were deposited and reduced by gelatin as a safe edible, naturally occurring and cheap support. No extra reducing agents were used for the generation of Pd(0) nanoparticles from the Pd(II) salt. The nanoparticles of Pd supported on gelatin were characterized by SEM, TEM and AFM images, UV-Vis and XRD spectra and the amount of palladium entrapped in the gelatin was measure...
